7 / 84 page EM78P417N/418N/419N 8-Bit Microprocessor with OTP ROM Product Specification (V1.0) 06.23.2005 • 1 (This specification is subject to change without further notice) 1 General Description EM78P417/8/9N is 8-bit microprocessors designed and developed with low-power and high-speed CMOS technology. It is equipped with a 4K*13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM). With its OTP-ROM feature, it is able to offer a convenient way of developing and verifying your programs. Moreover, it provides a protect bit to guard against code intrusion, as well as 3 Code Option words to accommodate your requirements. Furthermore you can take advantage of ELAN Writer to easily write your development code into the EM78P417/8/9N. 2 Features Operating voltage range: 2.3V~5.5V base on 0 °C ~ 70°C (commercial) 2.5V~5.5V base on –40 °C ~ 85°C (industrial) Operating frequency range (base on 2 clocks): • Crystal mode:DC ~ 20MHz/2clks, 5V; DC ~ 8MHz/2clks, 3V • RC mode: DC ~ 4MHz/2clks, 5V; DC ~ 4MHz/2clks, 3V Low power consumption: • Less than 2.2 mA at 5V/4MHz • Typically 15 µA, at 3V/32KHz • Typically 1 µA, during sleep mode 4K × 13 bits on chip ROM 144 × 8 bits on chip registers (SRAM) 3 bi-directional I/O ports 8 level stacks for subroutine nesting 8-bit real time clock/counter (TCC) with selective signal sources, trigger edges, and overflow interrupt 8-bit multi-channel Analog-to-Digital Converter with 12-bit resolution Three Pulse Width Modulation (PWM ) with 10-bit resolution One pair of comparators (can be set to act as an OP) Power-down (SLEEP) mode |
